Title: Method for producing alkenylthiophenols and their esters
IPC: C07C327/02
Filed: 1987-12-08
Abstract: A method is provided for preparing alkenylthiophenols, e.g. para-vinylthiophenol, or their esters, e.g., para-vinylthiophenol acetate by reacting a hydroxy aromatic ketone, e.g., 4-hydroxyacetophenone (4-HAP) with an N,N-di(organo)thiocarbamoyl halide, e.g., N,N-dimethylthiocarbamoyl chloride (DMTC) to form an O-(acylaryl) N,N-di(organo)thiocarbamate, e.g., O-(4'-acetophenyl) N,N-dimethylthiocarbamate, and pyrolytically rearranging the latter compound to form an S-(acylaryl) N,N-di(organo)thiocarbamate, e.g., S-(4'-acetophenyl) N,N-dimethylthiocarbamate. In one procedure, the latter compound is directly reduced to form an S-(1-hydroxyalkylaryl) N,N-di(organo) thiocarbamate, e.g., S-[4'-(1-hydroxyethyl)phenyl] N,N-dimethylthiocarbamate, which is either hydrolyzed to form a (1-hydroxyalkyl) thiophenol, e.g., 4'-(1-hydroxyethyl) thiophenol, which, optionally after acylation of its thiol group, is dehydrated to form the alkenylthiophenol wherein the double bond is at the ring-bonded carbon atom, e.g., para-vinylthiophenol, or the S-(1-hydroxyalkylaryl) N,N-di(organo) thiocarbamate is dehydrated to form an S-(alkenylaryl) N,N-di(organo) thiocarbamate, e.g., S-(4-vinylphenyl) N,N-dimethylthiocarbamate which is hydrolyzed to form the alkenylthiophenol. In an alternative procedure, the S-(acylaryl) N,N-di(organo)thiocarbamate is hydrolyzed and the resulting thiol acylated with an acylating agent, e.g., acetyl chloride, to produce an acylthiophenol ester, e.g., 4-acetothiophenol acetate, which is then reduced and hydrolyzed to produce the (1-hydroxyalkyl) thiophenol. The latter compound is then dehydrated to produce the alkenylthiophenol, or acylated and dehydrated to produce the alkenylthiophenol thioester, as described in the first procedure.

Filed: 1988-07-05
Abstract: In the case of a device for testing metallic work pieces, in particular welds, by means of magnetisable particles, a network of fine-filamented plastic is arranged in a container between a base film 10 and an outer film. The particles of magnetisable material are suspended in a liquid and, when a magnetic field is applied, form structures characteristic of any imperfections there may be in the work piece.

Title: Weighing apparatus and method
IPC: G01G3/142
Filed: 1988-03-03
Abstract: A load cell produces an oscillating signal indicative 
of the weight of the product. The maximum and minimum 
values of the oscillating signal are determined to provide 
a reference value which is an average of the maximum and 
minimum values. Using the reference value for the starting 
point and ending point, one cycle of the oscillating signal 
is identified and integrated to determine the corresponding 
weight of the product. The apparatus compensates for 
errors in the relationship between the actual starting and 
ending points of the cycle and the reference value.
Patent EP-0286416-A3 (EP)
Title: Method for real-time image generation
IPC: G06T15/20
Filed: 1988-04-08
Abstract: In a real-time computer-image generation 
system, processing resources for manipulating polygons 
that define objects are generally limited. This results 
in a trade-off with respect to the amount of detail to be 
displayed in an object versus the number and type of 
objects to be displayed. In order to save processing 
resources, the value of a predetermined viewing criterion 
is used to determine when an object can be represented by 
a single polygon. The single polygon is rotatable about 
a predetermined number of axes for maintaining a 
predetermined relationship with respect to a view-point. 
Since processing resources are saved by using a single 
polygon, additional objects and/or more detail may be 
included in a display.

Title: Echo canceller
IPC: H04B3/23
Filed: 1988-07-22
Abstract: An echo canceller (1) for full duplex digital data 
transmission in a transmitter/receiver unit when connected via a 
hybrid circuit (2) to one end of a two wire line (3). In order to 
provide adequate cancellation at a line data rate of 160 kbit/s over 
7-8 km, a data bit history of at least 9 bits is used to address a 
memory having at least 3 partitions (41-44) with the first partition 
(41) being addressed by a sequence of at least 3 data bits. This 
partitioning achieves a small memory size, less than 2 kbits, and a 
small total chip area for integrated circuit realisation of the 
canceller together with a clocking speed for moderate power 
consumption is maintained by using serial arithmetic (61-63) for 
adding the partition outputs together with pipelining (D1, D21 - D24). 
An exponentially quantitising analogue-to-digital converter error 
signal circuit (9), shown in detail in Figure 2, is used which has 
wider application to echo cancellers other than the partitioned memory 
compensation type.
